Răspuns:

Explicație pas cu pas:

a)

1 + 2 + 3 + 4 + ...+ 99 = 99*100/2 = 99*50 = 4950

1,4^4950

b)

2 + 4 + 6 + ....+ 100 = 2*(1 + 2 + 3 + ...+ 50) = 2*50*51/2 = 50*51 = 2550

2,5^2550

c)

1 + 3 + 5 + ... + 101 = 1 + 2 + 3 + 4 + 5 + ....+ 101 - (2 + 4 + 6 + ...+ 100)

= 101*102/2 - 2550 = 101*51 - 2550 = 5151 - 2550 = 2601

2,25^2601

d)

2*3*5*7 = 210

210 + 1000 = 1210

1,7^1210
